I have an '87 420 SEL that will is not starting. The problem began when I replaced the rubber bushing on the shift leakage. The reason for repalacing the bushing was because I would have to move the shifter to and from Park/Drive in order to start the car. Immediately following the replacement everything seem to be working fine! It will start as it should when the shifter was in the PARK position. Unfortunately, after just a couple of days the car began doing the same thing. I will then move the shifter from Park to Drive and back and the car will start. However, now no matter what I do it just will not start! What do I to get the car started?
